Take an example out of more advanced math. Pupils observe how basic algebraic concepts help solve expressions from higher level math courses. The video from a Mathispower4u Algebra 1 series shows the evaluation and simplification of the difference quotient using algebraic manipulations learned in a beginning algebra course.
